2,3-Dihydro-2,3-bismethylenebenzothiophene, a Reactive Annellated Diene

Dyker, Gerald,Kreher, Richard P.

, p. 1203 - 1206 (2007/10/02)

The cis configurated annellated diene 4 is generated in solution by the reaction of the easily accessible 2,3-bis(bromomethyl)-benzothiophene (3) with sodium iodide.In the presence of CC or NN dienophiles cycloaddition reactions take place and lead to 5, 6, 11, and 12 with acceptable yields.This annellation method is useful for the synthesis of polycyclic compounds.
